Technical Field

[0001] The utility model belongs to the technical field of seedling raising drip irrigation, and particularly relates to an agricultural seedling raising circulating drip irrigation device. Background Technique

[0002] Soilless seedling raising is a new technology used in modern plant cultivation. That is, instead of using soil, a non-soil solid material is used as a substrate, and nutrient solution is poured, or without using any substrate, hydroponics or fog cultivation is used for seedling raising. The existing devices cannot realize the recycling of the nutrient solution for seedling raising, and can avoid the waste of the nutrient solution.

[0003] In the seedling raising drip irrigation circulation system, the nutrient solution that is dripped into the soil but not absorbed by the plants will enter the liquid storage tray, and then enter the liquid storage basin. During this process, impurities in the soil may enter the liquid storage basin along with the liquid flow, which may cause the pipeline to be blocked during subsequent circulating drip irrigation. Therefore, an agricultural seedling raising circulating drip irrigation device is needed, which can filter the liquid in the circulation system to avoid the situation that impurities in the soil block the circulation pipeline, thereby ensuring the smoothness of the circulating drip irrigation.
